Spectroscopic Ellipsometry of Conducting Anisotropic Pedot thin Films

Macromolecular Rapid Communications, EarlyView.
We measure the optical response of poly[3,4‐ethylenedioxythiophene] thin films through the combination of polarized photon spectroscopies (variable‐angle ellipsometry, UV–mid‐IR reflectance and transmittance) and wide‐angle X‐ray scattering, revealing anisotropic optical response and conductivity and enabling structural modelling of chain and π‐system ...

On the analyzing of bifurcation properties of the one‐dimensional Mackey–Glass model by using a generalized approach

Mathematical Methods in the Applied Sciences, EarlyView.
The goal of this work is to look at how a nonlinear model describes hematopoiesis and its complexities utilizing commonly used techniques with historical and material links. Based on time delay, the Mackey–Glass model is explored in two instances. To offer a range, the relevance of the parameter impacting stability (bifurcation) is recorded.

The Combined Effects of Variable Viscosity and Thermal Conductivity of An Unsteady Casson Fluid Flow Along a Vertical Porous Channel With Convective Cooling Walls, Using the Bivariate Spectral Local Linearization Method

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This study examines the combined impact of different thermal conductivity and viscosity on unsteady non‐Newtonian Casson fluid flow of incompressible, electrical conductivity in a porous vertical channel with convective cooling walls, uniform magnetic field, and constant pressure gradient.

Extension of the Lorentz symmetry up to conformal in the limit of ultrahigh energies

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011
The group-theoretical justification is presented for the original approach by Kirznits and Chechin which allows for the primary protons of ultra-high energy cosmic rays to overcome the energetic limit (about 50 EeV) of Greisen-Zatsepin-Kuzmin remaining in

Quantifying the Effects of Spatial Inhomogeneity in an Autoclave LDPE Reactor Using CFD

Macromolecular Reaction Engineering, EarlyView.
A CFD simulation incorporating rigorous polymerization chemistry into a plant‐scale sliding mesh reactor with multiple PID controllers revealed axial flow patterns that segment the reactor into smaller compartments with different properties. More evident differences exist between the mixture within the agitator shaft swept volume and that outside of ...

High‐Mobility and Low Carrier Concentration Transparent Conducting Oxide Rear Contact for Bifacial CIGS Solar Cells

Progress in Photovoltaics: Research and Applications, EarlyView.
This study investigates high‐mobility, low carrier concentration (CC) transparent conducting oxides (TCOs) as back contacts in bifacial Cu (In, Ga)Se2 (CIGS) solar cells. These TCOs enhance rear‐side light absorption in CIGS and external quantum efficiency, improving overall performance by offering high transparency, low reflectance, and maintaining ...

Tailorable Curie Temperature in Zinc Ferrite Nanoparticles With Finely Tunable Induction Heating Profiles Between Room Temperature and 250°C

Small, EarlyView.
A spray‐drying‐based synthesis enables the formation of zinc ferrite nanoparticles with customizable induction heating from room temperature to 250°C by varying the zinc content and postsynthesis annealing temperatures. The aqueous dispersions are colloidally stable and heat up to biologically relevant thresholds. Hence, this approach offers a scalable

2D Iron Oxide at the Graphene/SiC(0001) Interface

Small Methods, EarlyView.
2D iron oxide was successfully formed via intercalation of Fe and O into the graphene/SiC(0001) interface. Atomic‐resolution electron microscopy revealed that the 2D iron oxide is encapsulated by graphene and sharply interfaced with SiC. This material is suggested to exhibit antiferromagnetic behavior at low temperatures.
